Davey, P., 2009: A local species restricted to southern and western Britain, the larva feeding on birch (Betula spp.), alder (Alnus spp.), sallow (Salix spp.) and sweet chestnut (Castanea sativa). In Dorset, the moth is resident and evidently well established in the valley swamps of Powerstock Common where alder is dominant. Elsewhere, there is a single record from Monkton Wyld Wood in the far west of Dorset. Searches have failed to detect the moth in potential habitat elsewhere. Continued monitoring of this moth is recommended at Powerstock. The following example, a suspected immigrant, was recorded as warm south-east to easterly winds blew in from northern France: Scar Bank, at light on 12 July 1946 (AGBR).
